This article is from Sensors (Basel, Switzerland) , volume 11 . Abstract Wireless sensor networks (WSN) have been studied in a variety of scenarios over recent years, but work has almost exclusively been done using air as the transmission media. In this article some of the challenges of deploying a WSN in a heterogeneous biomass, in this case silage, is handled. The dielectric constant of silage is measured using an open-ended coaxial probe. Results were successfully obtained in the frequency...

This article is from Cell Division , volume 6 . Abstract Background: An oocyte undergoes two rounds of asymmetric division to generate a haploid gamete and two small polar bodies designed for apoptosis. Chromosomes play important roles in specifying the asymmetric meiotic divisions in the oocytes but the underlying mechanism is poorly understood. Results: Chromosomes independently induce spindle formation and cortical actomyosin assembly into special cap and ring structures in the cortex of the...

Here we consider as example, how to estimate mean survival time after a diagnosis of metastatic colorectal cancer from Norwegian register data on time to death or censoring binned into 30 day intervals. All events occurring in the first three months (90 days) after diagnosis were removed to achieve comparability with a clinical trial....

This article is from Sensors (Basel, Switzerland) , volume 11 . Abstract Multilayered microresonators commonly use sensitive coating or piezoelectric layers for detection of mass and gas. Most of these microresonators have a variable cross-section that complicates the prediction of their fundamental resonant frequency (generally of the bending mode) through conventional analytical models. In this paper, we present an analytical model to estimate the first resonant frequency and deflection curve...

Abstract Micro-Raman spectroscopy is a very promising tool for medical applications, thanks to its sensitivity to subtle changes in the chemical and structural characteristics of biological specimens. To fully exploit these promises, building a method of data analysis properly suited for the case under study is crucial. Here, a linear or univariate approach using a R2 determination coefficient is proposed for discriminating Raman...

This article is from Journal of Mathematical Neuroscience , volume 1 . Abstract We consider a conductance-based neural network inspired by the generalized Integrate and Fire model introduced by Rudolph and Destexhe in 1996. We show the existence and uniqueness of a unique Gibbs distribution characterizing spike train statistics. The corresponding Gibbs potential is explicitly computed. These results hold in the presence of a time-dependent stimulus and apply therefore to non-stationary dynamics.

As a result, many local false peaks may be generated in contrast measurements, making it difficult for the camera’s passive auto-focus system to perform its function of locating the focused peak. In this paper, a new passive auto-focus algorithm is proposed to address this problem. First, a noise reduction preprocessing is introduced...

This article is from Journal of Medicine and Life , volume 4 . Abstract Intradural extramedullary epidermoid (EC) cysts are uncommon (0,2–1%). Acquired tumors appear more frequently as a late complication of lumbar punctures (40%). The authors present three cases of epidermoid cysts of the cauda equina which were surgically treated in their department during the past five years. All three had suffered lumbar punctures for rachianesthesia 6–9 years prior to their presentation. The patients'...

This article is from Marine Drugs , volume 9 . Abstract Bacteria belonging to the Vibrionaceae family are widespread in the marine environment. Today, 128 species of vibrios are known. Several of them are infamous for their pathogenicity or symbiotic relationships. Despite their ability to interact with eukaryotes, the vibrios are greatly underexplored for their ability to produce bioactive secondary metabolites and studies have been limited to only a few species. Most of the compounds isolated...

This article is from Journal of Functional Biomaterials , volume 2 . Abstract This computational study investigates the sensing and actuating behavior of a pH-sensitive hydrogel-based microfluidic flow controller. This hydrogel-based flow controller has inherent advantage in its unique stimuli-sensitive properties, removing the need for an external power supply. The predicted swelling behavior the hydrogel is validated with steady-state and transient experiments. We then demonstrate how the...

This article is from Biology of Sex Differences , volume 2 . Abstract Background: Hypertension (HTN) exhibits sexual dimorphism; the incidence for women surpasses men during the sixth decade of life, while the pharmacological treatments are less effective and produce more side-effects in women than in men. Aerobic exercise (AE) has been shown to prevent and treat HTN; however, resistance exercise (RE) is not recommended as a strategy to treat HTN. In this study, we investigated the potential...

This article is from BMC Infectious Diseases , volume 11 . Abstract Background: Evidence in the literature suggests that exopolysaccharides (EPS) produced by bacterial cells are essential for the expression of virulence in these organisms. Secreted EPSs form the framework in which microbial biofilms are built. Methods: This study evaluates the role of EPS in Prevotella intermedia for the expression of virulence. This evaluation was accomplished by comparing EPS-producing P. intermedia strains...

This article is from Pharmacognosy Magazine , volume 7 . Abstract Objective:: To optimize the extraction technology for polysaccharides from the root of Limonium sinense (Girard) Kuntze, Plumbaginaceae and evaluate the antioxidant capacity of polysaccharides from L. sinense (LSEP) Materials and Methods:: One-singer factor and response surface methodology(RSM) were established to extract the polysaccharides from L. sinense. Then, the 1,1-diphenyl-2-picrylhydrazyl free radical, hydroxyl...

This article is from Pharmacognosy Magazine , volume 7 . Abstract Background:: Zingiber officinale Rosc. is not only an important medical plant in China, but also one of the most commonly used plant spices around the world. Early researches in Z. officinale Rosc. were focused on rapid propagation, germplasm preservation, and somatic embryogenesis, only a few reports focused on the generation of tetraploid ginger plants with colchicines treatment in vitro. Materials and Methods:: The...

This article is from Indian Journal of Community Medicine : Official Publication of Indian Association of Preventive & Social Medicine , volume 37 . Abstract Background:: Reproductive tract infections (RTIs) is a global health problem including both sexually transmitted infections (STIs) and non-sexually transmitted infections (non-STIs) of the reproductive tract. RTI/STI is an important concern, as it possess risk for human immunodeficiency virus transmission. Hence a community study was...

This article is from The FASEB Journal , volume 26 . Abstract About 30% of the population of the United States suffers from acute or chronic pain, often of unknown cause. Among this group might be included patients with symptoms claimed to be caused by a poorly defined condition called “chronic Lyme disease” in which chronic pain is a major contributor. Since there is no evidence to indicate that chronic Lyme disease is due to a persistent infection and that extended antibiotic therapy is...

This article is from BMC Systems Biology , volume 5 . Abstract Background: Design of newly engineered microbial strains for biotechnological purposes would greatly benefit from the development of realistic mathematical models for the processes to be optimized. Such models can then be analyzed and, with the development and application of appropriate optimization techniques, one could identify the modifications that need to be made to the organism in order to achieve the desired biotechnological...

This article is from Diagnostic Pathology , volume 6 . Abstract Mesothelioma of tunica vaginalis is a rare neoplasm, typically demonstrating frankly malignant morphology and aggressive behavior. Rare cases of well-differentiated papillary mesotheliomas have also been reported, which, in contrast, demonstrate indolent behavior. There are, however, cases which do not fit into the well-differentiated or diffuse malignant mesothelioma categories and can be considered mesothelioma of tunica...
